You, my love, are playing against the German (4,6)
I believe the answer is:
dear reader
'you' is the definition.
I know nothing about this answer so I can't tell whether this works.
'my love are playing against the german' is the wordplay.
'my love' becomes 'dear' (I am not sure about this - if you are sure you should believe this answer much more).
'playing' is an anagram indicator.
'against' is a charade indicator (letters next to each other).
'the german' becomes 'der' ('the' in German).
'are' anagrammed gives 'rea'.
'dear'+'rea'+'der'='DEAR READER'
Can you help me to learn more?
I've seen this clue in the Evening Standard.
